Curator of the exhibition Numbers versus humanity

In this exhibition we show the importance that the number has in all disciplines of knowledge and human activities. The numbers appeared 5,000 years ago even before the language and writing. It is very possible that millions years before Lucy had already looked to the sky to contemplate the sun (the one) the star (the two) and the stars (many). Since the appearance of numbers humanity has become a very complex set of people whose behaviors are analyzed using algorithms based on numerical information. The curious thing about all this, is that if life fits a series of numbers with a small margin of error, it turns out that at present , the future of humanity lies in the numerical value of a series of big questions that we have raised and that are intimately related to their past, present and future. In other words, the sustainable future of humanity can be analyzed from the numerical information of several parameters related to all human activities. That is why our exhibition, which will recreate the number in all disciplines of human knowledge, is intertwined with the so-called Sustainable Development Goals of the UN, which, well analyzed, are fundamentally numbers associated to each objective: zero hunger, the numbers of our energy reserves, the number of inhabitants and their future projection, the city and rural areas, livestock and agriculture, the environment and climate change, etc.

In our exhibition there are panels that explain the appearance and history of the number, the numbers of human knowledge in law, economics, journalism, agriculture, livestock, physics, chemistry, geology, biology, transport ("mobility"), ecology, population in rural areas and cities, distribution of wealth, energy consumption by economic sectors, numbers of life, etc. There are also placed a series of projectors that send information from different global number counters in real time: world population, water consumption, energy reserves, energy produced and consumed, aging of the population, emigration, deaths due to wars, accidents, diseases, environmental pollution, car production, books sold, number of people connected to the internet at every moment, numbers of emails sent per minute per day, deforestation, CO2 pollution, number of undernourished people, number of obese people, etc.

2.- The exhibition consists of 20 panels and each panel contains, on average, 14 cartoons. All the information we show has been verified by specialists and many of the cartoons have a totally original design. Among the cartoons are projected a set of numbers that come from accountants who in real time report everything that happens worldwide
